The man suffered third-degree burns, Tunisia's national civil protection and civil defense authorities said.

He was taken to the same hospital where Mohamed Bouazizi was taken in December 2010.
Tunisia's bubbling unrest

Bouazizi, who died after setting himself on fire, was widely credited for spurring Arab Spring uprisings across North Africa and the Middle East.

The 26-year-old street vendor earned about $10 a day selling fruit.

But after a municipal inspector seized his belongings, Bouazizi doused himself with fuel and set himself ablaze in front of a government building.

The fatal protest unleashed a wave of regional dissent against unemployment, government corruption and stifled freedoms.
